Year in Review: Bay had his best year at the plate since 2005, posting a wOBA of .397 – good for 15th best in the league. The areas of his game that led to the great year were patience and power. He walked in 15% of his PA, the second-highest rate of his career (in 2006 he walked 15.2% of the time). In terms of power, his ISO (.269) and homers (36) were both career highs. The walks and power came at a price of more strikeouts, 30.5%, which was his highest level since 2004. The strikeouts resulted in a lower average of just .267. Hitting in the middle of an excellent Boston lineup, he had more than 100 runs scored and RBIs.

The Year Ahead: Bay ended up inking with the New York Mets and he should have ample opportunities for runs and RBIs – a very good shot at 100 of each. He is a solid power hitter and, depending on his new home park, he should be projected to hit between 25 and 30 homers. His average is modest, as he strikes out quite frequently, but it’s not as bad as some high-strikeout power hitters. Bay should throw in about 10 steals. He should provide solid contributions in three categories while not hurting you as much as other power hitters in the other two. Bay is a solid top-10 outfielder heading into 2010 who could see his numbers explode if those around him (David Wright, Jose Reyes) return to their old ways. (Dave Allen)

Profile: Jason Bay has put up .230+ ISOs every year in his career save two -- 2007 and last year. The thing is, that massive drop in power cannot be attributed to his home field alone -- not only did he play poorly on the road (.112 ISO away from Citi) as well as home (.182 ISO), but the park also didn't suppress power as much as most may have thought (94 park factor for home runs by RHB). Looking across his batted-ball types, Bay didn't suddenly start beating the ball into the ground or anything. Instead, the two poor years have one thing in common: the worst reach rates of his career. Perhaps he was pressing. Will all that time off help push him from the spotlight and tamp down expectations? If that is the case, it's possible that he doesn't press as much in 2011, doesn't reach as much, and finds his power stroke once again. Power drops this extreme are rare, and he's only 32, so it's not quite time for him to fall from grace this quickly. (Eno Sarris)

The Quick Opinion: Call it a lost year for the Canadian slugger, who was putting up career-worst power numbers even before he lost the second half of the season to concussion symptoms. He has to bounce back, doesn't he?

Profile: Despite average-ish batting averages on balls in play and a strikeout rate within a sniff of the league number, Bay has settled in with a bad batting average. That might be okay if he had his old power, but that disappeared with his move to the National League. He'll still steal you double-digit bags because he's aware on the basepaths, and with a little love from the new walls in Citi Field, he might be able to manage 15-20 home runs in 2012. Still, if that comes with a mediocre batting average, it's not that useful. Pick him in your final rounds if your outfield could use some help, but don't put too many eggs in that basket. (Eno Sarris)

The Quick Opinion: Oh baybee, Jason's lost what we need. The power's gone, the batting average has tanked, and Mets fans are ready for the day he's no longer patrolling left field in Citi. At least they moved the walls in!

Profile: Following a surprise separation from the Mets after three disappointing years (91 wRC+), the 34-year-old Bay wound up in Seattle, close to his British Columbia home. Safeco Field is traditionally death to righties, but the walls are coming in this year and Bay has always had the ability to go the other way, particularly with power. The logjam at first and DH shouldn't cut into his playing too much as a left fielder, but he figures to see most of his action against left-handed pitchers. He'll never be the 30/100/100 guy he was back in the day, but there's at least some hope Bay can be (deep-league) fantasy relevant going forward. Just not much. (Mike Axisa)

The Quick Opinion: Bay has the kind of opposite field pop to overcome Safeco Field's righty-hating ways, but his days of 30/100/100 are long gone. The change in addresses may help, but it's going to take a lot more than that for the former Rookie of the Year to be fantasy-useful.

Profile: When the Seattle Mariners brought Jason Bay to Spring Training, it seemed like a decent buy-low option in an attempt to find lightning in a bottle. Bay, once a highly productive outfielder with the Pittsburgh Pirates and briefly the Boston Red Sox, was coming off a particularly miserable run with the New York Mets from 2009 to 2012, and his fantasy value was essentially nil. And when he was done in Seattle, his fantasy value was no better. Bay managed to hit just .204/.298/.393 and you can't say "it's over" more aptly than being released by a team in desperate need of offense. Bay's future is probably more uncertain than at any time in his career, and it remains to be seen if he lands a major league assignment in 2014. If there was anything to be optimistic about, it's that his isolated slugging percentage was at a three-year high at .189, and it's not completely ridiculous to think a club will give him a shot in a friendlier environment to hit other than Seattle. But even if Bay lands somewhere, it's likely to be in a bench role and therefore not at all useful to your fantasy squad. (Michael Barr)

The Quick Opinion: Jason Bay hasn't been a good baseball player since 2009. He's 35 and he doesn't currently have a job. Pray you don't need him on your fantasy team.
